This is a Kungs icescraper. It features replaceable blades. Great idea: when it's spent, just replace the triangular blade. The problem is, you can only use 3 edges on one side of the blade. When t...
The triangular blades come with two straight edges and one angled, serrated edges. The two straight edges work equally well front and back. The serrated edge only work as intended, like a chisel.
In fairness, there is one valid reason why the company would have chosen to make it impossible to reverse the blade: to avoid support calls and warranty claims from people trying to use the serrated edge the wrong way around.
Because if you think about it, they went out of their way to make the socket one-way: it would actually be cheaper to manufacture the notch on both sides than the way they made it on one side only. So they really did intend to ensure the blade can only be mounted one way.
But here’s the thing: you have to be really, REALLY dumb to use the serrated edge in reverse and not realize it. It’s completely obvious that the tool isn’t working right, and there’s something sharp sticking up instead of down on the glass. So I don’t buy the idiot-proof anti-warranty-claims argument: I’m totally certain it is done to limit the life of the blades.
Although mind you, it’s rather academic: when an edge is spent, I simply sharpen it with a fine belt on the belt sander and it’s good for another few months anyway 🙂 But of course, you need a belt sander if you want to do that.
The one I have looks pretty much the same, but one of the edges is straight, one is concave and the last one is serrated. Maybe the concave edge is also designed to work only one way. If so, it makes sense to prevent the user from flipping it over.

I really feel like you place a lot of faith in the competence and observational skills of the public at large.
